A novel organic pollutants gas sensing material p-type CuAlO2 microsphere constituted of nanoparticles for environmental remediation

- Ozone gas sensing CuAlO2 microspheres were successfully prepared by wet chemical route.
- Oxidation (O3 and NO2) and reduction (NH3 and CO) toxic gas sensing properties were systematically investigated.
- It is exhibited real-time response for very low detection 200 ppb at 200 °C, with fast response (29 s), recovery (45 s) time, to ozone gas.
